◆ Using special superfine fiber of small aperture AGM partition and tight assembly process to avoid short circuit fault;

◆ The battery case is made of reinforced ABS plastic, sealed up with modified epoxy resin sealant, corrosion preventive and no acid leakage;

◆ The electrolyte is made of high purity sulfuric acid and special additives, to ensure maximum performance of electrode and suppress short circuit and self discharge;

◆ Normal use without acid replenishment or water replenishing, free maintained; if influenced by working conditions that losing a lot of water, you can add distilled water to ensure the normal performance of the electric property;
